Definitions
- acetaldehyde acetaldehyde
- AA acetaldehyde
- the container market for carbonated and still mineral water requires exceptionally low levels of acetaldehyde (AA) in the container side wall in order to avoid the diffusion of the AA into the water leading to an undesirable water taste.
- AA is an inherent side product which is generated during the polymerization melt phase and subsequent processing steps.
- variables such as catalyst selection influence the amount of residual AA.
- this level of AA is still perceived to be too high for some applications.
- taste testing has indicated that humans can taste 20 ppb differences in AA. Consequently, there has been significant interest in reducing the residual AA content as low as possible.
- the present invention involves naphthalenedicarboxylate polyester/polyamide blends having surprisingly low AA.
- the present invention further discloses naphthalenedicarboxylate containing polyester/polyamide blends which are formed by mixing a polyester base resin with a concentrate containing the polyamide.
- polyester (A), of the present invention is selected from polyethylene naphthalenedicarboxylate (PEN) or copolyesters thereof.
- the acid component of polyester (A) contains repeat units from at least about 50 mole percent naphthlenedicarboxylic acid and at least about 50 mole percent ethylene glycol, based on 100 mole percent dicarboxylic acid and 100 mole percent diol.
